Concept of a USB sand clock. 3D holographed material inside the glass that you can make changes.
Pick a color, length of time and material and the inside of the sand clock changes accordingly.

Oh my god. What you just invented is called an hourglass. It’s been around for hundreds of years. At least I won’t have to go through the annoyance of having to look at the clock in the lower right hand corner of the screen.
Very interesting, but I don’t see how this is an improvement over the traditional hourglass.
Thanks for the comments. The biggest difference is that you can customize the material inside the glass from the desktop.
